Nerve Blocking Electrode Guide for Safe Vessel Wall Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode apparatuses struggle to accurately and safely enclose the outer walls of tubes in the body, such as blood vessels, without damaging them, while effectively delivering electrical impulses to nerves for procedures like renal denervation.
Innovation Solution
An electrode apparatus with an electrode guide and driving units, including a motor interlocking system, allows precise control over the electrode's contact with the tube's outer wall, using a combination of motors to regulate tensile force and movement, ensuring safe and accurate attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode unit is brought into close contact with the tube wall to effectively denervate or modulate the nerves, then the therapeutic effect is improved, but the risk of damaging the tube wall increases
Solution Approach 1:
The electrode guide acts as an intermediary component between the electrode unit and the tube wall. It provides a guiding structure that directs the electrode unit to enclose the tube circumferentially while preventing direct harmful contact with the tube wall, thus enabling effective nerve modulation without causing damage
Solution Approach 2:
The electrode guide is designed to be movable in the radial direction, allowing it to dynamically adjust its position. This dynamic capability enables the electrode unit to be precisely positioned for effective nerve contact while the guide maintains a protective distance from the tube wall, resolving the contradiction between therapeutic effectiveness and safety
2Reliability
If the component including the electrode is made to enclose the outer wall of the artery circumferentially to effectively denervate the nerves, then the therapeutic effectiveness is improved, but the complexity of precisely locating and attaching the component increases
Solution Approach 1:
The electrode guide serves as a mediator that simplifies the positioning process. Its structure is designed to naturally enclose the tube when deployed, providing self-alignment features that guide the electrode unit into the correct circumferential position without requiring complex external positioning mechanisms
Solution Approach 2:
The electrode guide is pre-configured with a structure that enables it to enclose the tube circumferentially upon deployment. This preliminary structural arrangement eliminates the need for complex real-time positioning adjustments, reducing operational complexity while ensuring therapeutic effectiveness
3Stability of the object's composition
If the electrode unit is attached to the outer wall of the tube to maintain stable contact for nerve modulation, then the stability of contact is improved, but the risk of damaging the easily damaged tube wall increases
Solution Approach 1:
The electrode guide acts as a protective intermediary that maintains stable contact between the electrode unit and the tube wall without transferring damaging forces to the tube. The guide's structure distributes contact forces safely, enabling stable electrode positioning while protecting the vulnerable tube wall from damage
Solution Approach 2:
The electrode guide provides a cushioning effect by being positioned between the electrode unit and the tube wall. This pre-positioned protective layer absorbs and distributes mechanical stresses, preventing direct damage to the tube wall while maintaining stable contact for effective nerve modulation
